Can anyone tell me if they have upgraded a 7ECA from the O235 to the O360 or some other engine? I am being told buy some local owners that this is a pretty common upgrade. It must require an STC does anyone know of one? Is it worth the trouble or should I stay with a 115hp. I am either going to upgrade or sell it and buy a Decathon I'm thinking because I'm getting close to needing to do an engine. What advise do you have for me.
